Getting information about the network in CIDR notation
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Given an IP address, the ``ipaddr()`` filter can produce the network address in CIDR notation.
This can be useful when you want to obtain the network address from the IP address in CIDR format.
Here's an example of IP address::
ip_address = "{{ ansible_default_ipv4.address }}/{{ ansible_default_ipv4.netmask }}"
'192.168.0.11/255.255.255.0'
This can be used to obtain the network address in CIDR notation format::
# {{ ip_address | ipaddr('network/prefix') }}
'192.168.0.0/24'
